Description

本発明は、複数の成分を混合し、且つその混合物を分配するためのチップ（ｔｉｐ）に関する。本チップは成分をバルク供給する場合の使用に特に適している。本チップはさらに、反応物質を混合し及び分配するのに特に適している。   The present invention relates to a tip for mixing a plurality of components and dispensing the mixture. The chip is particularly suitable for use when supplying ingredients in bulk. The chip is further particularly suitable for mixing and dispensing reactants.

［発明の背景］
材料の混合及び材料の分配の両方を行うチップ（先端部）は当該技術分野で知られている。例えば、米国特許第５，２４９，８６２号は、歯科用印象材を混合し及び分配するのに特に適したそのようなチップを開示している。多くの状況では、複数のプレミックス成分は、単一のバルク貯蔵装置の別個の領域等に別々に収容される。或る量の成分混合物が必要とされる場合、別個の成分が混合用チップに流入され、ここで混合され、次いで、混合用チップから分配される。このことは、例えば塩基及び触媒を歯科用印象材に用いる場合にも当てはまる。このような形式の混合用チップは多くの場合、電動式（動力式）バルク貯蔵装置との使用を伴い、電動式バルク貯蔵装置により、混合用チップ内のステータ（ｓｔａｔｏｒ）にトルクが与えられ、ステータが回転して、成分の混合が行われ混合された成分が押し進められ、チップを介して分配される。 [Background of the invention]
Tips (tips) that both mix materials and distribute materials are known in the art. For example, US Pat. No. 5,249,862 discloses such a tip that is particularly suitable for mixing and dispensing dental impression materials. In many situations, multiple premix components are housed separately, such as in separate areas of a single bulk storage device. If a certain amount of component mixture is required, the separate components are flowed into the mixing tip where they are mixed and then dispensed from the mixing tip. This is also true when, for example, a base and a catalyst are used in the dental impression material. Such a type of mixing tip often involves the use of an electric (powered) bulk storage device, and the electric bulk storage device imparts torque to the stator in the mixing tip, The stator rotates, the components are mixed, and the mixed components are pushed and distributed through the chip.

上記‘８６２号特許に示されているように、成分間の交差汚染（ｃｒｏｓｓ−ｃｏｎｔａｍｉｎａｔｉｏｎ）は、それが所要となるまで、可能な限り回避されるべきである。バルク貯蔵装置自体内の成分間のいかなる交差汚染も、装置の出力を遮断するおそれがあるか、又は成分を尚早に反応させるおそれがある。このような状況はいずれも一般に望ましくない。   As shown in the '862 patent, cross-contamination between components should be avoided as much as possible until it is required. Any cross-contamination between components in the bulk storage device itself can block the output of the device or cause the components to react prematurely. Both of these situations are generally undesirable.

したがって、複数の材料を混合し及び分配するためのチップ、特に、バルク貯蔵装置とともに用いるように設計されたチップが必要とされている。かかるチップは、バルク貯蔵装置内の又はその出口流路内の望ましくない交差汚染を防止するのを促進するようなものであるべきである。かかるチップは、成分を均質に混合する能力に関して改良されるべきである。   Therefore, there is a need for chips for mixing and dispensing multiple materials, particularly chips designed for use with bulk storage devices. Such a chip should be such as to help prevent unwanted cross-contamination in the bulk storage device or in its outlet flow path. Such a chip should be improved with respect to the ability to mix the ingredients homogeneously.

［発明の開示］
複数の成分を混合し及び分配するためのチップは、バルク貯蔵装置内に設けられた相補的な出口流路に個々に対応する伸張型（ｅｘｔｅｎｄｅｄ）給送流路を有する。チップ内に設けられた給送流路の数は、バルク貯蔵装置内に設けられた出口流路の数と少なくとも同数とするべきであり、この数は多くの場合、バルク貯蔵装置内に貯蔵されている個々の成分の数に対応する。ここでの考察のため、本発明は、本明細書ではそのような給送流路を２つ有するものとして説明する。混合用チップ内に設けられた給送流路は、当該技術分野において従来知られているものよりも伸張されており、交差汚染を効果的に防止するものであるため、混合用チップは、次の手順に備えて取り外されるまで、バルク貯蔵装置用のキャップとして用いることができる。 [Disclosure of the Invention]
A chip for mixing and distributing a plurality of components has an extended feed channel that individually corresponds to a complementary outlet channel provided in the bulk storage device. The number of feed channels provided in the chip should be at least the same as the number of outlet channels provided in the bulk storage device, which is often stored in the bulk storage device. Corresponds to the number of individual components. For purposes of discussion here, the present invention will be described herein as having two such feed channels. The feeding flow path provided in the mixing tip is extended more than that conventionally known in the art and effectively prevents cross-contamination. It can be used as a cap for a bulk storage device until it is removed in preparation for the procedure.

給送流路は、成分を混合するのに適した断面を有するように構成され、その断面に基づき、所定量の各成分をチップの混合領域に入れるようになっている。必要とされる各成分の量は異なることがあるので、そのため、各給送流路の断面は異なっていてもよく、又は、必要であれば同じであってもよい。また、流路の長さは、使用前には、バルク貯蔵装置にある出口流路内の各成分の液位（ｌｅｖｅｌ）が前の使用により相対的に等しくなるように構成されることができる。これにより、次の手順の際に各成分の浪費が少なくなる。   The feed channel is configured to have a cross section suitable for mixing the components, and based on the cross section, a predetermined amount of each component is placed in the mixing region of the chip. Since the amount of each component required may be different, therefore, the cross section of each feed channel may be different or the same if necessary. Also, the length of the flow path can be configured such that, prior to use, the liquid level of each component in the outlet flow path in the bulk storage device is relatively equal prior to use. . This reduces the waste of each component during the next procedure.

混合用チップはステータ部材及びハウジングを有する。混合用チップのステータは、チップのハウジングの後壁に接触もせず、またかすりもしない。そこに生じる空隙により、湾曲パドルが案内する生成物の流れが妨げられやすくなる。生成物は、混合部材又はステータの周りを流れる際、掃引されてハウジングの首部に入る。ハウジングは、生成物を混合するとともに混合した生成物をチップから押し出しやすくする複数の、好ましくは４つの内部成形された螺旋形のねじ山（ｌａｎｄ）及び溝を有する。ステータは、ステータ上に、好ましくは長手方向に配置された混合部材を有し、ステータが回転する際に、混合部材が成分を物理的にねじ山及び溝に接触させるようになっている。これにより、成分が混合され、混合用チップ内を長手方向に移動してその内部に設けられた排出孔へ入る。   The mixing chip has a stator member and a housing. The mixing tip stator does not contact or scrape the rear wall of the tip housing. The resulting air gap tends to hinder the product flow guided by the curved paddle. As the product flows around the mixing member or stator, it is swept into the neck of the housing. The housing has a plurality of, preferably four, internally molded helical threads and grooves that facilitate mixing the product and forcing the mixed product out of the chip. The stator has a mixing member disposed on the stator, preferably in the longitudinal direction, such that when the stator rotates, the mixing member physically contacts the components to the threads and grooves. As a result, the components are mixed, move in the mixing chip in the longitudinal direction, and enter the discharge hole provided in the inside.

［発明を実施するための好ましい形態]
混合用チップ１０は、バルク貯蔵装置１１とともに用いられるように構成されることが好ましい。例示のため、バルク貯蔵装置１１は、２つの別個の成分区画室１２及び１３を有するものとして示されている。バルク貯蔵装置１１は、使用時点で、従来の電動式分配装置（図示せず）とともに用いられることが好ましい。バルク貯蔵装置１１は、電動式分配装置内に配置され、力の作用により、バルク貯蔵装置の区画室１２及び１３内の材料を、混合用チップ１０が近接して位置している排出端へ向けて押し込むか又は流し込むようになっている。 [Preferred Mode for Carrying Out the Invention]
The mixing chip 10 is preferably configured to be used with the bulk storage device 11. For illustration purposes, the bulk storage device 11 is shown as having two separate component compartments 12 and 13. The bulk storage device 11 is preferably used with a conventional motorized dispensing device (not shown) at the point of use. The bulk storage device 11 is arranged in an electric distribution device, and by the action of force, the material in the compartments 12 and 13 of the bulk storage device is directed to the discharge end where the mixing chip 10 is located in close proximity. Push or pour.

したがって、混合用チップ１０は、初めに区画室１２及び１３内に保持され得るような複数の成分を混合及び分配するのに有用である。混合用チップ１０は、バルク貯蔵装置にある相補的な出口流路２２及び２３にそれぞれ対応する伸張型給送流路２０及び２１（図７）を有することが好ましい。チップ内の給送流路の数は、バルク貯蔵装置にある別々の出口流路の数と少なくとも同数とすべきであり、この数は多くの場合、バルク貯蔵装置内に貯蔵される個々の成分の数に対応する。この検討のため、本発明は、本明細書ではそのような給送流路を２つ有するものとして説明される。「相補的な」とは、２つの給送流路が、例えば圧入（ｐｒｅｓｓ ｆｉｔ）等により、物理的に協働して、バルク貯蔵装置１１から混合用チップ１０へ、最終的に混合用チップ１０の排出孔３０へひと続きの経路を形成することを意味する。一実施形態では、バルク貯蔵装置１１にある出口流路２２及び２３は、このようなひと続きの経路を形成するようにそれぞれ伸張型給送流路２０及び２１を物理的に受け入れるソケットを形成している。   Thus, the mixing tip 10 is useful for mixing and dispensing a plurality of components that can be initially retained in the compartments 12 and 13. The mixing tip 10 preferably has elongate feed channels 20 and 21 (FIG. 7) corresponding respectively to complementary outlet channels 22 and 23 in the bulk storage device. The number of feed channels in the chip should be at least as many as the number of separate outlet channels in the bulk storage device, which is often the individual component stored in the bulk storage device. Corresponds to the number of. For this review, the present invention is described herein as having two such feed channels. “Complementary” means that the two feed channels are physically co-operated, eg, by press fitting, to the mixing chip 10 from the bulk storage device 11 and finally the mixing chip. This means that a series of paths to the ten discharge holes 30 is formed. In one embodiment, the outlet channels 22 and 23 in the bulk storage device 11 form sockets that physically receive the extension feed channels 20 and 21, respectively, to form such a continuous path. ing.

混合用チップの給送流路は、当該技術分野においてこれまで既知のものよりも伸張しており、これにより交差汚染を効果的に防止することができるので、混合用チップは、次の手順のために取り外されるまで、バルク貯蔵装置用のキャップとして用いることができる。当該技術分野で以前から既知の混合用チップにあっては、比較的短い給送流路が設けられていた。本発明によれば、混合用チップ１０の給送流路２０及び２１は、混合用チップ１０の長さの約１／４〜３／４、より好ましくは約１／２の長さになるように伸張している。当然のことながら、給送流路２０及び２１は、給送流路がより短い場合に知られていた交差汚染を効果的に防止するのに十分な長さである限り、本発明で規定する範囲よりも長くとも短くともよく、また、その範囲内にあってもよい。   The mixing chip feed flow path extends beyond what is known in the art so that cross-contamination can be effectively prevented. Can be used as a cap for bulk storage devices until removed. In mixing chips that have been known in the art for some time, a relatively short feed channel was provided. According to the present invention, the feed channels 20 and 21 of the mixing tip 10 are about ¼ to ¾, more preferably about ½ the length of the mixing tip 10. Is stretched. Of course, the feed channels 20 and 21 are defined in the present invention as long as they are long enough to effectively prevent the cross contamination known when the feed channels are shorter. It may be longer or shorter than the range, and may be within the range.

給送流路２０及び２１は、各成分を混合するのに適した断面を有するように構成され、その断面に基づいて、所定量の各成分をチップの混合領域に入れるようになっている（図２）。必要とされる各成分の量は異なる場合があり、そのため、給送流路の各断面は異なっていてもよく、又は、必要であれば同じであってもよい。流路の長さは、使用前には、バルク貯蔵装置にある出口流路内の各成分の液位が前の使用により相対的に等しいように構成されることもできる。これにより、次の手順の際に成分の浪費が少なくなる。   The feed flow paths 20 and 21 are configured to have a cross section suitable for mixing each component, and based on the cross section, a predetermined amount of each component is placed in the mixing region of the chip ( Figure 2). The amount of each component required may be different, so each section of the feed channel may be different, or the same if necessary. The length of the channel can also be configured so that, prior to use, the liquid level of each component in the outlet channel in the bulk storage device is relatively equal prior to use. This reduces waste of components during the next procedure.

混合用チップは、ステータ部材３１、上部ハウジング３２、および下部ハウジング３３を有する。下部ハウジング３３は給送流路２０及び２１を保持し、好ましくは、給送流路２０及び２１と一体形成される。上部ハウジング３２は、下部ハウジング３３に恒久的に又は一時的に取付け可能であるように構成されることで、その内部のステータ部材３１が、内部で自由に回転することができるような態様で捕捉される。この取付けは、接着、溶接等を含めた任意の手段によるか、又は例えばリップ４０と回り止め４１との間の物理的接触及び協働作用等による、ラッチ機構との物理的相互作用により達成され得る。上部ハウジング３２には、ステータ受入れ部５１に通じるベース部５０が設けられることが好ましい。ステータ３１にも同様に、ステータベース部６０及び細長部６１が設けられ、使用の際、細長部６１がステータ受入れ部５１内に受け入れられるようになっている。ステータ３１の細長部６１には、好ましくは細長部６１から長手方向に突出する突出部７０が設けられる。突出部７０は、以下に説明するような態様で、上部ハウジング３２と物理的に相互作用及び協働作用を行う。   The mixing chip includes a stator member 31, an upper housing 32, and a lower housing 33. The lower housing 33 holds the feed channels 20 and 21 and is preferably formed integrally with the feed channels 20 and 21. The upper housing 32 is configured to be permanently or temporarily attachable to the lower housing 33, so that the stator member 31 therein can be captured in such a manner that it can freely rotate inside. Is done. This attachment is accomplished by any means including gluing, welding, etc., or by physical interaction with the latch mechanism, such as by physical contact and co-operation between the lip 40 and the detent 41. obtain. The upper housing 32 is preferably provided with a base portion 50 that communicates with the stator receiving portion 51. Similarly, the stator 31 is provided with a stator base portion 60 and an elongated portion 61, and the elongated portion 61 is received in the stator receiving portion 51 during use. The elongated portion 61 of the stator 31 is preferably provided with a protruding portion 70 that protrudes from the elongated portion 61 in the longitudinal direction. The protrusion 70 physically interacts and cooperates with the upper housing 32 in the manner described below.

ステータ部材３１のベース部６０には、複数の掃引用混合部材７１を設けることが好ましい。さらに好ましくは、ステータのベース部６０には、第１及び第２の組の掃引用混合部材７１が設けられる。掃引用混合部材７１は、湾曲していることが好ましい。図５に示すように、第１の組の湾曲掃引部材７１ａは、第２の組の湾曲した掃引用混合部材７１ｂに対し離隔した対向関係で位置する。これにより、ステータ部材３１がどの方向に回転しようとも問題なく掃引混合が可能となる。ステータ部材３１を分配装置の動力駆動部（図示せず）に取り付けて、上述したトルク力を与えて上部ハウジング３２内のステータ部材３１を回転させるようにする何らかの手段が設けられる。例えば、コレット（ｃｏｌｌｅｔ）３４が、ステータ部材３１に取り付けられるか、又はステータ部材３１と一体形成されて、例えばかかる電動式装置と物理的に相互作用（図示せず）させることができる。さらに、ステータ部材３１には、任意の数及び形状の中間の掃引パドル又は混合部材、例えばパドル７２等を設けることができる。   It is preferable to provide a plurality of sweep mixing members 71 on the base portion 60 of the stator member 31. More preferably, the base portion 60 of the stator is provided with a first and second set of sweeping and mixing members 71. The sweeping and mixing member 71 is preferably curved. As shown in FIG. 5, the first set of curved sweep members 71a are positioned in an opposing relationship spaced apart from the second set of curved sweep mixing members 71b. As a result, sweep mixing can be performed without any problem no matter which direction the stator member 31 rotates. Some means is provided for attaching the stator member 31 to a power drive unit (not shown) of the distributor and applying the torque described above to rotate the stator member 31 in the upper housing 32. For example, a collet 34 can be attached to the stator member 31 or integrally formed with the stator member 31 to physically interact (not shown) with such an electric device, for example. Further, the stator member 31 can be provided with an intermediate number of swept paddles or mixing members of any number and shape, such as the paddle 72.

ステータ部材３１は、所定位置にあるときに下部ハウジング３３に接触もせずかすりもしないことが好ましい。その間に形成される空隙８０によって、掃引用混合部材７１により方向付けされる生成物の流れが妨げられやすくなる。生成物は、ステータ部材３１の周りを流れる際、掃引されて上部ハウジング３２のステータ受入れ部５１に入る。   It is preferable that the stator member 31 does not contact or rub against the lower housing 33 when in the predetermined position. The voids 80 formed therebetween tend to hinder the product flow directed by the scavenging mixing member 71. As the product flows around the stator member 31, it is swept and enters the stator receiving portion 51 of the upper housing 32.

上部ハウジング３２は、内表面を有するように中空であることが好ましい。上部ハウジング３２の内表面は、複数の、好ましくは４つの、内部に成形された螺旋形ねじ山９０を有し、このねじ山９０は、生成物を混合し、混合された生成物を混合用チップ１０から押し出しやすくする。ステータ部材３１の突出部７０は、ステータ部材３1に取り付けられるか、又は、より好ましくはステータ部材３１と一体形成されて、ステータ部材３１が回転する際に突出部７０により成分を物理的にねじ山９０に接触させるようになっている。これにより、各成分は、混合され、混合用チップ１０内を長手方向に移動してその内部の排出孔へ入る。上部ハウジング３２のねじ山９０は、一重螺旋、二重螺旋、又はそれによりも多い数の螺旋ねじ山を含めた、任意の構造を有し得る。二重螺旋ねじ山９１が図４に示されている。   The upper housing 32 is preferably hollow so as to have an inner surface. The inner surface of the upper housing 32 has a plurality, preferably four, internally molded helical threads 90 that mix the product and mix the mixed product. It is easy to push out from the chip 10. The protrusion 70 of the stator member 31 is attached to the stator member 31, or more preferably integrally formed with the stator member 31, and the component is physically threaded by the protrusion 70 when the stator member 31 rotates. 90. As a result, the components are mixed, move in the mixing chip 10 in the longitudinal direction, and enter the discharge holes therein.
